IMPROVEMENT IN WIRE-WORK.

Specification forming part of Letters Patent No. 70,946, dated November19, 1867.

To all whom it may concern.-

Beit known that I, WANNIBALD R. BOERNER, ot' Chicago, in the county ofCook and State of' Illinois, have invented a new and useful Improvementin Wire-Work; and I do hereby declare that the following is a full,clear, and exact description ofthe same, reference being had to theaccompanying drawing and theletters and gures marked thereon, which forma part otl this specilication, and in which- Figurel represents asideelevation of apiece of my improved Wire-work.

The nature of my invention l.consists in a novel way ot' bending andputting together wire so as to form rm and compact wire-Work in whichthe wires will all be kept in place more securely than in ordinarywire-work.

The main wires which constitute the wirework have angles bent in them inopposite directions, at suitable distances apart, for the binding-wireB, said distances depending upon the size of the wire and the coarsenessofthe work. The binding-wires are two wires twisted together, as clearlyshown in the drawing. The angles in the main wires A are so arranged inputting the work together that two of said wires pass through thetwisted wire together, and said angles extend above and below the lineot' direction of the main wire alternately, as clearly shown in thedrawing. By this arrangement the main Wires A will not turn in thetwisted wires and become displaced; neither will the twisted wires slidelaterally on the main wires, and thereby destroy the uniformity and atthe same time weaken the structure of the Wire-work.

I do not limit myself` to any particular anglein the wires A, for acurve or any kind ot' a bend would make substantially the same kind otlwork, neither do I limit myself to wires twisted together, for Iconsider that any coustruction whereby two bent Wires pass through thesame loop and accomplish the two results above specified-that is,preventing the turning of' the main wires and the lateral sliding of thebinding-wires--is my invention.

Having fully described the construction and operation,wl|ut I claim, anddesire to secure by Letters Patent, is-

Vire-Work to be used for any purpose, when constructed substantially asherein described.
